23 Claims.

The present invention relates to an improvement in knock downcontainers, which are machine made of paper board, shipped flat inbundles to the distributor, and erected, lled and Y One of the featuresof the present structure is in the provision in a container having widefront and rear walls and relatively narrow side walls, of a series ofinterconnected end closing flaps and webs, to close the container ends,these all being located on the opposite ends of the body forming panels,and adapted, upon manual manipulation of some of the end flaps to moveto closing position to 'cause all of the other end aps and webs toautomatically move to end closing position.

A further feature is in the provision of an added positive end lockingtuck ap on one of the container ends, whereby when the end flaps areclosed, the lock flap automatically locks the closed end to form acontainer bottom and compels destruction thereof to open same.

The foregoing and other features will be apprehended as the hereindescription proceeds and it is obvious that modications may be made inthe present structure, Without departing from the spirit thereof or `thescope of the appended claims.

In the drawings,

Fig. 1 is a layout of the container blank showing the various end apoutlines and score lines;

Fig. 2 is an open, plan or end view of the blank of Fig. 1, showing thegeneral contour of the present form of container;

Fig. 3 is an end view of the openable and-reclosable top end of thecontainer, with end flaps in closing position;

Fig. 4 is a fragmentary, side view of the top end ofthe containershowingthe top end aps about, to be closed; f

Fig.5 is a view similar to Fig. 4, showing the top end closing flapsnearly closed; g

Fig. 6 is a view similar to Figs. 4 and 5, showing the top end flapsentirely closed; l

Fig. 7 is a bottom view of the container sho ing thebottoxn closingflaps closed with the botton tucking lock ap inoperative and bent awayfrom its adjacent wall;

Fig. 8 is a bottom view, in plan, showing the tucking lock iiap inentered position, unlocked;

Fig. 9 is a View like Fig. 8, showing the flap lock in end closing andlocking engagement;

Fig. 10 is a fragmentary perspective view of the reclosable top apclosure, partly closed;

Fig. 11 is an end view in plan showing the top end closure as applied toa hexagonal container with symmetrical body forming sides as in theabove noted pending application; and

Fig. 12 is an end view of the container partly collapsed on its scorelines c-f.

As indicated in Figs. 2 and 11, the container may be made up in twoforms, one a completely symmetrically sided hexagonal form as in Fig.11, and the other in a six sidedV form, trans--y versely having twowide, opposed side walls A-D joined at their edgesby opposed triangularside walls C-Band E-F, as in Fig. 2. The container of Fig. 11 maycontain round bottles, for instance, and the container of Fig. 2 maycontain at bottles, such as, for instance, pint whiskey bottles ofstandard type.

Further there is shown herein two end clos- Y ing flap closures bothidentical in the main elements thereof but one form preferably forming aclosable and openabletop end closure known as a reclosable cover, andthe other forming, preferably, a closable andv lockable bottom endclosure known as a locked cover, which after locking in closed positionwill sustain the contained load without dropping it through the bottom,when the container is lifted.

It is intended that the present container be closed, locked at thebottom against opening and closed at the top, to be opened and reclosedat will, preferably without the use of glue, for sealing, though theends may be glue sealed if desired.

As will hereinafter appear, the end closures are easily operated andeach of them make a tight closure proof against inadvertent opening,when closed, and, incidentally, because of the plural overlapping foldsin the end closures they form a shock absorbing cushion for the bottleends.

The blank layout of the present improvement is shown in Fig. 1, and itcomprises the main body forming panels A-B-C-D-E and F,V with the bodyglue lap G, attached to panel F, all of these panels and lap beingdefined from one another by parallel bodyscore lines` b-c-d-e-f and g.

Each of the body panels are of the same height as viewed in Fig. 1,being bounded by traversing summon, top and bottom score lines,generally de- Cil and locking elements thereof shown at the lower4 endof the blank.

The top end forming elements, comprise aps .and webs, the flaps beingindicated by V-H-I- y J-L-M and the connecting webs being indicated by.p-q-r-s, the said latter webs being connected between flaps I-J-L andM, and being defined by angular score lines 'i-i-lc--l so that flaps IandY L are triangular with the base of lthe triangle formed by thecommon score line O.

The webs q and r from their triangular score lines :i and k extendupwardly along both edges of main flap J and are defined therefrom byscore lines .m and n, main flap J is defined from main panel D by commonscore line O. Flaps M and H are defined from triangular webs s and p byvertical score lines c and f.

Glue lap G terminates at its upper and lower edges h-h at the commonscore lines N and O.

Main body panel A has its lower edge z terminated at the score line Nand at its upper opposite edge is provided with a tuckable locking flapV defined 'from A by common score line O, and having a second spacedaway score line v traversing its width.

'I'he bottom forming /closure elements, Fig. 1, comprise main flapsH-I--J-L-M, and the flap connecting Webs are\indicated by p-q-r.-s, theconnecting .webs being defined from their associate flapsY by scorelines z'-7`-k-Z, so that, as in the arrangement of the' upper endclosing flaps, the flaps I-J and L are triangular and are defined fromtheir triangular webs by angular score lines z'-a-k and l. All of thebottom end forming aps and webs are defined from the body panels bycommon score line `N.

Main end closing ap J has a tuck lock flap K on its outer end, which isdefined from flap J by a score line w and this tuck lock nap, on each ofits opposite ends, has scored therefrom, as at :1J-y, a latch tab t andu, respectively.

Both upper and lower main aps J have their triangular webs q and. rextended on their opposite edges, said webs being scored from flaps J byscore lines m and n, which are actually extensions of body score lines dand e.

The blank is glued on the front face of the glue lap G, as viewed inFig. 1, and then bent backwardly on its score lines c and f, and theglue lap is attached to the inside face of body panel A, at or near itsedge a. As thus described, the container is flat, as partially shown inFig. 12 but unlike Fig. 12, has none of its score lines, other thanscore lines c and f broken, and

as so folded may be piled in bundles for shipment to user ordistributor.

-When the distributor sets the container up for use he rst bends thescored blank on the score lines b-d-e and g until the container body isin the form shown in the end view in Fig. 2. The score linesy of the endclosing flaps and connecting. webs may then be. operated to close thecontainer. i

To close thefupper reclosable end, the erected container blankisarranged so that body panel A faces the operator as in Fig. 10, flapsH and M also `face lthe operator, and these are simultaneously pinchedtowards their attached diagonal webs p and s respectively on score linesc and f, until these vflaps and webs contact, then the flaps are bentrearwardly yon score line O. bending webs p and s inwardly on theirrespective score lines i and b.

Continued downward and inward pressure on laps H and M pull flaps I andl inwardly and downwardly, this in turn bending webs q and r on theirscore lines i, lc, l, m and n, which action draws main top flap y'towards operator, about as shown in Figs. 4 and 10. Near the nal closureof the main top flap J, the two side webs q and r have been folded underJ, and, with J, form an open spout end, into which the end of frictiontuck flap V, by bending inwardly on its secondary I score line o isintroduced, as in Fig. 5, and then J is pushed down all the way toclosing position as in Fig. 6, and friction tuck flap V finally pushedin all the way, finally bending on its score line O. Thus, flap V isfrictionally caught inside main iiap J and its two coacting locking websp-r, which, when the top end is closed firmly grasp and hold thefriction tuck ap V between them, as indicated in dotted lines, Fig; 3.

The same sequence of action is followed in closing the lower, bottomforming elements except that -the main lower cover ap J is fully closeddown, covering, as in the top closure, al1 of the coacting elements, butleaving the lock flap K and its two resilient latches t and uoutstanding as in Fig. 7 With the main lower ap J nearly closed there isleft an opening along the lower edge z of body panel A, between flaps Hand M,

and the latches t and u. are bent under all the Way until they contactwith the under face of lock ap k, and then flap 1c with the bent overlatches are tucked through the opening at edge z and downwardly into thecontainer interior. Upon the nal entry of the` lock ap Ic into thecontainer as in Fig. 8, the latches t and u being there shown dotted,the latches spring outwardly into,

be proportioned to form a polygonal hex shaped container having all ofits body forming panels of the same width, thus to form a true hexagonalcontainer as in Fig. 11, without any change in the end closing elementsexcept as to modifications in dimensions of the various body panelwidths.

However the preferred form of container is that shown in all figuresexcept Fig. 11, the preferred container comprising major body formingpanels A and D and aps, and the minor body forming panels B, C, E and F,as and their flaps, by this latter arrangement of the panels thecontainer is` easily adapted to receive bottles of at, rectangular andout of round shapes. Y

Itis herein to be noted that the reclosable closure as in Figs. 2 and 3,for instance may be used on either or both ends of the container, or thetuck lock structure of Figs. 7, 8 and 9`may also be used on either orboth ends of the con- Y tainer or both used as shown and describedherein.
